Abstract
The utility model discloses a transmission shaft, which comprises a universal joint fork (4) and a cross shaft, wherein a group of convex splines (3) are processed at the position of a flange end face (1) of the universal joint fork (4) of the transmission shaft; two side surfaces of the universal joint fork (4) are provided with dust covers (5). The above technical scheme is adopted in the utility model, utilize the setting of splined connection and shield, its purpose provides a high bearing capacity, high reliability, light in weight, the transmission shaft for car of dust proof. The running safety of the machine is ensured, and the service life of the transmission shaft is prolonged.
Description
Technical field
The utility model belongs to the technical field of mechanical transmission connection set, and more particularly, the utility model relates to a kind of automobile transmission shaft.
Background technique
At present, in traditional truck drive shaft, flange end all adopts bolt to connect, the seam location, torque is born by bolt, when transmitting torque greatly, if still adopt this Placement, just need to increase the diameter of connecting screw rod, or increase bolt quantity, the physical dimension of transmission shaft and assembly weight will correspondingly increase.Control for transmission shaft dynamic balance accuracy and car load vibrations all is totally unfavorable; Moreover the connection part of cross axle has lubricant oil, can make universal-joint fork and cross axle wearing and tearing with dust for a long time, thereby has influenced the working life of transmission shaft.
The model utility content
Problem to be solved in the utility model provides a kind of transmission shaft, and its objective is provides a kind of high bearing capacity, and high reliability is in light weight, the automobile transmission shaft of dust protection.
To achieve these goals, the technological scheme taked of the utility model is:
This transmission shaft provided by the utility model comprises universal-joint fork 4 and cross axle, and flange end face 1 position of the universal-joint fork 4 of described transmission shaft processes one group of convex surface spline 3; In the bi-side of universal-joint fork 4 dust cover 5 is installed.
For making the utility model more perfect, more detailed and concrete technological scheme below also further having proposed, to obtain best practical effect, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
Described convex surface spline 3 is positioned at the position in connecting screw rod hole 2.
Described convex surface spline 3 be shaped as four sections rings.
Described dust cover 5 is screwed on the bi-side of universal-joint fork 4.
Described dust cover 5 is circular.
The size of described dust cover 5 matches with the cross axle mounting hole of universal-joint fork 4 sides.
The utility model adopts technique scheme, utilizes the setting of spline connection and dust cover, and its objective is provides a kind of high bearing capacity, and high reliability is in light weight, the automobile transmission shaft of dust protection.Guarantee the Security of machine run, prolonged the working life of transmission shaft.
Description of drawings
Below expressed content of the accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model,
Be labeled as among the figure:
1, flange end face, 2, screw hole, 3, spline, 4, universal-joint fork, 5, dust cover.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present invention, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
As the structure of the present utility model that Fig. 1 expresses, be a kind of transmission shaft, comprise universal-joint fork 4 and cross axle.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize saving cost, the technological scheme that replacing makes things convenient for goal of the invention, the utility model to take is:
This transmission shaft provided by the utility model, flange end face 1 position of the universal-joint fork 4 of described transmission shaft processes one group of convex surface spline 3; In the bi-side of universal-joint fork 4 dust cover 5 is installed.
Screw hole 2 connection parts of transmission shaft output flange end face 1 process one group of concave surface annular spline 3, process another group concave surface spline that matches with transmission shaft at screw hole 2 connection parts of transmission shaft flange end face 1, connect with bolt again.Dust cover 5 is installed on the universal-joint fork 4, prevents that dust from entering, and causes cross axle and universal-joint fork 4 wearing and tearing.Prolonged the working life of transmission shaft.
Be the concrete exemplifying embodiment that the utility model provides below, for those skilled in the art's reference and selecting for use when implementing the utility model:
Embodiment one:
Convex surface spline 3 described in the utility model is positioned at the position in connecting screw rod hole 2.
Described convex surface spline 3 be shaped as four sections rings.
Screw hole 2 connection parts of transmission shaft output flange end face 1 process one group of concave surface annular spline 3, process another group concave surface spline that matches with transmission shaft at screw hole 2 connection parts of transmission shaft flange end face 1, connect with bolt again.
Embodiment two:
Dust cover 5 described in the utility model is screwed on the bi-side of universal-joint fork 4.
Described dust cover 5 is circular.
The size of described dust cover 5 matches with the cross axle mounting hole of universal-joint fork 4 sides.
In the bi-side of universal-joint fork 4 dust cover 5 is installed, so just can prevents that booties such as the dust and the grains of sand from entering cross axle and universal-joint fork 4 the insides, these parts wear and tear.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
